Hi MikeyG,
One thing you might try is to disconnect the cutter from the computer and retry the autoload process. Sometimes there may be data that your computer is still trying to send to the cutter that may be causing it to feed further than normal. If the problem persists when the cutter isn't connected to the computer then I would try doing a factory reset to clear any corrupted data that might be causing these issues.
Please don't hesitate to contact Summa technical support at (800)323-9766 if you need a hand troubleshooting this issue further.
Thanks!
Best regards,
